I'm glad you mentioned Sunshine, as it is incredibly underrated, and has excellent music, acting, and camerawork. It is a shame that is barely known outside of England.
And Hot Fuzz was amazing. Me and my dad picked it at random while we were stranded in a movie theater in Budapest because of the rain. We had no idea what it was about, and it turned out to be one of the best chances we took.
Though I have to ask, am I the only one who found Let The Right One In not only greatly overrated, but just bad in general? It just seems like that sort of tedious, soulless kind of artsy movie that I notice a lot in Europe? I'm not saying it doesn't have artistic merits, but the dialog is pointless and overdone, the acting stoic and one-dimensional, and the dynamics non-existent. Maybe I'm just some dumb American who gets off on instant gratification (one step ahead, eh?), but I do expect a certain amount of emotional grounding in my movies, not just pontificating just for the sake of seeming like you've made something suspenseful and worthy of further investment.
But anyways, Return of the King rocked my world. Good choice.
